heal.abstract	In this paper a model to find the approximate equations for determining the transverse modulus of elasticity of a unidirectional fibre-reinforced composite material from the constituent material properties is described. The classical theory of elasticity was applied to the simplified model of a composite unit-cell. Stress functions were applied to the fibre and matrix with boundary conditions requiring continuity of displacements across the fibre-matrix interface (perfect bonding was assumed). Graphical results are shown for glass-epoxy composites. The numerical results are compared with experimental data. The transverse elastic modulus, derived by applying the model introduced in this paper, seems to explain the experimental results fairly well. In the second part, assuming a viscoelastic behaviour of the matrix, the correspondence principle has been applied to the relationship of the transverse modulus of elasticity and the storage and loss moduli of the composite have been calculated. These theoretical values are compared with the experimental ones. © 1982.	en
